Portland needs to tweak its roster. There are good players — LaMarcus Aldridge, Gerald Wallace — but the backcourt can no longer count on Brandon Roy to lead every night.

The Blazers are looking to make a tweak in the draft by getting Connecticut point guard Kemba Walker, who led his team to the national championship last season. And they are willing to make a big trade to do it, according to the Portland Tribune.

The Trail Blazers, who own the 21st pick, are looking to move up in the June 24 draft.

According to a league source, Portland would like to get into the top seven to be in position to take Connecticut point guard Kemba Walker. That might mean packaging veteran point guard Andre Miller and the No. 21 pick for another team’s player along with a top-seven pick.

Of course, the Blazers are not talking officially.

Seventh may not be high enough, both NBC’s Rotoworld and DraftExpress have Kemba Walker going No. 5 overall to Toronto. Potential trading partners would be limited to Utah at three, the Cavaliers at four (who are drafting Kyrie Irving No. 1 so don’t expect them to trade for Miller) and Toronto.

Andre Miller has a very reasonable one year, $7.8 million on his contract for next year.
